Definitions

  • the present invention relates to types for a typewriter or similar machine :and especially for types with boldface type characters.
  • boldface type character is herein used to designate a type character in which the impression produced by the type is not substantially in line form but makes an imprint of relatively wide area.
  • a clear and clean print is, however, not always obtainahle with such boldface type characters, but the printed characters often have hazy or slightly blurred outlines giving the print an unequal appearance.
  • the present invention includes in a type for a typewriter or similar machine with boldface type characters, a type body having a top surface, a type character projecting from said top surface of said type body and having a relatively wide front face and being formed at least at the outer outline of said front face with a continuous upwardly extending projection.
  • the continuous projection is formed along all edges of the front face of the type character.
  • the type may also include an additional projection projecting from the top surface of the type body adjacent the front end thereof for facilitating adjustment of the type on a type bar. This projection may extend transversely across the top surface of the type body adjacent the front end thereof and it may be formed with a central notch.
  • FIG. 1 is a partial perspective view showing a type according to the present invention on an enlarged scale
  • FIG. 2 is a partly sectioned side view of the type shown to a further enlarged scale with the type shown during initial contact with the typewriter ribbon before penetration :of the same by the edges of the type.
  • the type of the present invention includes a type body 1 having a top surface 2 from which two boldface type characters 3 and 3a project.
  • the two characters 3 and 3a which are illustrated in FIG. 1 by way of an example as a capital R and a small letter r are in the usual manner longitudinally spaced from each other and from the front end of the type body 1.
  • the type characters 3 and 3a each have a relatively wide front face 4 and 4a respectively and are formed along the edges of the front faces thereof with continuous projections 5 and 5a respectively.
  • These projections 5 and 5a are of substantially triangular or wedge-shaped cross section as most clearly shown in FIG. 2.
  • the type is also provided with a projection 6 of substantially triangular cross section projecting from the top surface of the type body transversely across the same adjacent to the front end thereof and this projection 6 is preferably provided with a central notch 6a.
  • Projection 6 and notch 6a serve to properly align the type on a type bar of known construction, not shown in the drawing.
  • the typewriter ribbon 3 will be struck by the continuou projections 5 or 5a and the typewriter ribbon 8 will thereby be sharply pressed along the outline defined by the respective projection against the paper 9 srndwiched between the typewriter ribbon 8 and the platen 7.
  • the height of the projections 5 and 5a is made so small that the cavities defined by the projections 5 and 5a and the front faces 4 and 4a are respectively filled by a portion of the typewriter ribbon 8 during the impact of the type character so that the total front surface of the respective character will be properly imprinted.
  • Types of the present invention will therefore produce a perfect uniform sharply delineated imprint of the respective characters so that the print produced will have a perfect appearance.
  • a cylindrical roller having a predetermined radius of curvature and adapted to support on its curved outer face a typewriter paper; a typewriter ribbon having a predetermined thickness and adapted to be located superimposed upon typewriter paper located on said roller; and a type adapted to be placed adjacent the outer face of the typewriter ribbon and including a type body having a top surface facing said typewriter ribbon but located spaced therefrom and a type character projecting from said top surface of the type body and having a Wide front face spaced from said tion and said front face together defining a cavity having a depth less than said predetermined thickness of said typewriter ribbon so as to betadapted to be filled with a portion of said typewriter ribbon upon impact of said continuous projection on said ribbon, whereby a proper imprint of an area equal to that of the whole front face ofsaid type character is produced on said typewriter paper.
  • a cylindrical roller having a predetermined radius of curvature and adapted 'to support on its curved outer face a typewriter paper; a typewriter ribbon having a predetermined thickness and adapted to be located superimposed upon said typewriter paper located on said roller; and a type adapted 'tobe placed adjacent the outer face of the typewriter adapted to engage the same, said continuous projection and said front face of each of said type characters to-' gether defining a cavity having a depth less than the predetermined thickness of said typewriter ribbon so as to be adapted to be filled with a portion of said typewriter ribbon upon impact of said continuous projection on said ribbon whereby a proper imprint of an area equal to that of the whole front face of the respective type character is produced onssaid typewriter paper, and a projection extending transversely across and upwardly from said top surface of said body adjacent the front end thereof and being formed with a central notch.
